For the physical realization of such a set-up we have in mind, for example, semiconductor quantum dots coupled to an ensemble of nuclear spins in the host material or molecular orbitals coupled to a local magnetic moment. Using a semiclassical approximation, we derive a set of Ehrenfest equations of motion for the electron density matrix and the mean value of the external spin (Landau equations): Due to ","authors_text":"Gerold Kiesslich, Klemens Mosshammer, Tobias Brandes","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2012-06-26T14:01:56Z","title":"Transport and semiclassical dynamics of coupled quantum dots interacting with a local magnetic moment"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1206.5994","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:4ce95d83f52f0b98af48f50953254cbf399986591cb9c1ba7cca2bdfa71363e7","target":"record","created_at":"2026-05-18T03:41:32Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"540ae9864d38e6d5cf7a50902f98cd979a2d880680e00566f8fe2d10fec0456e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2012-06-26T14:01:56Z","title_canon_sha256":"cd0efc2d52332fae87ba438f2c068c6ee6710be4e375f491b384c226ed07ebb6"},"schema_version":"1.0","source":{"id":"1206.5994","kind":"arxiv","version":2}},"canonical_sha256":"f8ff2203acae4963796e572dea033697253babdce4253a36ff79bb4648c47681","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f8ff2203acae4963796e572dea033697253babdce4253a36ff79bb4648c47681","first_computed_at":"2026-05-18T03:41:32.042665Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:41:32.042665Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jmcE5Vj0+pZmYSDKm6RhFeagtUJ7c5Lt28xfQ8icsrm18znj2ozcnmx1DAL+fhYPBSWxxaKOQ57/rWZpDd3eDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:41:32.043409Z","signed_message":"canonical_sha256_bytes"},"source_id":"1206.5994","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4ce95d83f52f0b98af48f50953254cbf399986591cb9c1ba7cca2bdfa71363e7","sha256:2d7544cc937d58762d15e516f1746ef67fcf4d43493e63e0a6bd23c5f3139cce"],"state_sha256":"ad6f20575882ff31b776030e2a850f80a56e0b7ce23ee9c45570616387b18439"}
